I scored a bunch of logs from the local Coast Guard base that were used as rub rails for the last 60 years, still in perfect condition of course. I was told that they are greenheart. I plan to slab them out, not sure what they’ll end up as but it’ll be good experience.

I’m trying to learn more about them from the embossing on the end.
Can anyone help decipher this stamp?

All I can make out is S F and C.

Looks like a loggers stamp. Used much like a cattle brand to keep the log and loggers ID together.

There are catalogs of the various stamps, but being that the wood is most likely imported, finding the logging company info may be a challenge 8^)

Logs to be sold on the open market must have a stamp before the mill can purchase them. It is a traceable brand to help prevent theft of timber.

+1 The entire symbol is log brand.

Need a much clearer picture to get any help.

Never seen a national data base of log brands. Tend to be state registered in USA.

Can look at this one from Oregon as reference. They have currently over 3,500 registered log brand owners with approximately 10,000 log brands.

Need to contact Alaska DNR about lumber/log brand registration, if the logs were found in Alaska.
From Dept of Forestry Regulations:

Sec. 45.50.270. Publication of current list of brands. The department shall publish a list of brands as of December 31 of each even numbered year. The list must show the design of each brand, the name and address of the owner, the date of
Alaska Forest Management Statutes and Regulations, 2010 STATUTES 41
registration, and any transfer of a brand during the previous two years. Copies of the list shall be available to the public upon request. (§ 6 ch 51 SLA 1953; am § 8 ch 168 SLA 1970; am § 6 ch 68 SLA 1975)

Best Luck.

Just don’t try to milk them for all they’re worth.

I have no input on the stamp, but I looked up greenheart on the wood-database because I had never heard of it before. Very interesting stuff, it’s one of the stiffest woods that exists. You might want to take some precautions when sawing it, as the site warns that it can violently split apart when sawing (!?).

I also found this:

Wow, thanks for the link about the sawmills. I plan on using a full face shield when working it.

It’s definitely dense! It took two of us struggling to barely get one 8” x 5’ log in the truck!

A friend milled a log using a metal blade on the band saw and said it went well but very slowly.

I might make marimba keys out of it. My keyboardist tapped the two logs with a knuckle and determined that one is tuned to “C” and the other in “A flat”.
